Thanks for the replies everyone. I had it apart a while ago, I
remember checking out the gears, but don't remember the condition they
are in. If memory serves, it does fall off on every range. We do
have a working one that we use as the standard, so we'll probably keep
this one as a part unit, I was just wondering if it was a quick-n-easy
so we could have two (as is I have to run an 8 ft coax to a test bench
whenever I do power meters). Again, thanks for the replies, I'll
probably just leave it in the stock-pile of old stuff for future use,
there's other things that need fixin that get priority.

Thanks,
Steve
